(Friends to lovers to strangers..) Kim Hongjoong was your boy best friend, and no one could separate you guys. Till one day, he confessed his love for you, and you confessed your love for him. You both dated for 2 years until he became distant and... fell out of love..? So.. you both took a break from each other and broke up. Then, you both became strangers... On a Saturday afternoon, you take a walk in the park and get on the swings. You sit there and swing as you admire the kids playing.
